CLAP -> MIDI controller stuck notes.

[STOP63]

CLAP version 24d4a4b
Reaper 6.64+dev0803
Stuck midi notes when a MIDI controller keyboard is played.
No issue with VST3i version

Cannot confirm over here locally.

[STOP63]

I know from Reaper forum but did you test with a real keyboard? Mine are M-Audio Axiom61 and a Roland A-34.
No issue with VST3 plugin.

[mkruselj]

Yes, tested with Korg nanoKEY Studio and NI S49mk2. All works.

You don't happen to have surge in MPE mode do you @STOP63

[STOP63]

What is MPE mode?

Just want to be clear. I drag Surge XT VST plugin in Reaper everything is default and it work when I play with my keyboard.

I close Reaper

I re-open Reaper I drag Surge XT CLAP plugin in Reaper everything is default and all the notes that I play on the keyboard get stuck.

Same with Reaper portable.

Right there is a light button next to patch browser that says “mpe” between zoom and tune. is it lit up in the clap in reaper?

can you record and send an rpp file?

and are all your notes on the same midi channel?

appreciate the report - sure we can solve it

[STOP63]

OK MPE not activated but i tried it on and same issue.

I tried USB AXIOM61 > channel 1 only and same issue.

Here is a rpp file

Looks like somehow release velocity data is corrupted (see Reaper's MIDI event list). It should say 0 instead of --. Or maybe Reaper isn't handling release velocity towards CLAP very well. Forwarding your RPP to Reaper devs.

Considering sustain pedal works fine over here (and in Bitwig), I'm not sure if this is on our side to fix.

[STOP63]

Never mind the sustain pedal, I just mention the sustain pedal (on the dev reaper thread forum) to explain what it sound like. I used the term like if the sustain pedal was applied.

[mkruselj]

Well ok, even regularly played notes, works just fine here. I can't get any stuck notes...

[baconpaul]

Yeah I’m traveling today but let me load the rpp and see what it actually sends surge! That should help us triangulate

which reaper by the way? Still the 0803 one?

[STOP63]

Yes, still the 0803 one.

[mkruselj]

From schwa: "that is most likely the 0x90 + velocity=0 note-off protocol, which should be handled for the next REAPER build".

Closing since it's not on our side.

[STOP63]

Maybe but I have to mention that the CLAP version of "ODIN II" work fine.

[STOP63]

It work! +dev0804
